Mrs Sher gave Julie and Emily some money each on Tuesday. On Wednesday, Julie gave
15 of the amount she had to Emily. On Thursday, Emily gave
14 of the amount she had to Julie. In the end, Julie had $58 and Emily had $30. How much did Emily had more than Julie at first?

$88 |
Amount that Emily had in the end = 3 p
3 p = 30
1 p = 30 ÷ 3 = 10
Working backwards.
Amount that Julie had after giving to Emily on Wednesday
= 58 - 1 p
= 58 - 10
= $48
4 u = 48
1 u = 48 ÷ 4 = 12
Amount that Julie had at first
= 5 u
= 5 x 12
= $60
Total amount that Julie and Emily had
= 58 + 30
= $88
Amount that Emily had at first
= 88 - 60
= $28
Amount that Julie had more than Emily
= 60 - 28
= $32
Answer(s): $32
